عرفت A ..
بس رسمة b جننتني ..

اما السؤال b .. فواضح من الرسمه ان c طالع عن الماسك

[dan_dan]

كيف نستطيع ان نميز كل نوع ؟

[dan_dan]

في ا نتظار رد

[dan_dan]

802.11b
802.11g
802.11n

هل هذه هي الانواع المقصودة

[dan_dan]

a for blutoth
b for gsm-edge
c for iee802.11b

ان شاء الله يكون الحل صحيح

هذا مقال عن انواع التكنلوجيا الوير لس حاب استفيد ونتناقش فيه كمان الله يوفقكم

. WiFi: WiFi, the most popular wireless standard for networking computer systems, has the following basic characteristics:

– Multi-user configuration

– IEEE 802.11b data rate is 11Mbps

– IEEE 802.11g data rate is 54Mbps

– Frequency band is the 2.4Ghz band

– Range of 100-150 feet

– Equipment and WiFi systems/access points are usually privately owned
اي وحده فيهم هما خمسه بس لازم نعرف مين الي بيعمل عمليات نقل اتمنى تفيدوني

[dan_dan]

^^^هذا حل اي فقرة
---------------
b) Which of the practical signal(s) is (are) in violation of these masks and why?
مين يقدر يشرح لنا المطلوب

اعتقد ان شاء الله ان ده الحل الصح
يبقي باقي الجزء التاني من السؤال وانا اعتقد ان الحل هيكون 801.11b
due to noise
بس مش متاكدة من الفقرة b
ياريت حد يأ كد الحل

يبقى نحدد transmitter masks

بالنسبة للفقرة a

اما فقرة b هل تكفي الاجابة بهذا الشكل في حال كانت صحيحة ؟!

[dan_dan]

^^ يمكن انا فاهم السؤال غلط
هو طالب شيئين في السؤال
the 3 transmitter masks and mention the 3 popular wireless technologies a) Identify

اما الفقرة الثانية قصدت ان في حال جاء التاكيد من احد الزملاء على ان الاجابة صحيحة هل الكلمتين تعطي الطالب 5 درجات
لان الفقرة عليها 5 درجات

802.11 WLAN standards
The most common wireless standard for wireless local area networks (WLAN) is the 802.11 standard by IEEE. While there are also other standards as well as proprietary technologies, the benefit of 802.11 wireless standards is that they all operate in a license-free spectrum, which means there is no license fee associated with setting up and operating the network. The most relevant extensions of the standards are 802.11b, 802.11g, 802.11a and 802.11n.
802.11b, which was approved in 1999, operates in the 2.4 GHz range and provides data rates up to 11 Mbit/s. Until 2004, most WLAN products sold were based on 802.11b.
802.11g, which was approved in 2003, is the most common 802.11 variant on the market. It operates in the 2.4 GHz range and provides data rates of up to 54 Mbit/s. WLAN products are usually 802.11b/g compliant.
802.11a, which was approved in 1999, operates in the 5 GHz frequency range and provides data rates of up to 54 Mbit/s. An issue with the 5 GHz frequency range is that it is not available for use in parts of Europe where it is allocated for military radar systems. In such areas, 5 GHz WLAN components should conform to 802.11a/h standard. Another disadvantage with 802.11a is that its signal range is shorter than 802.11g’s because it operates on a higher frequency; consequently, many more access points are required for transmission in the 5 GHz range than in the 2.4 GHz range.
IEEE 802.11n is the new generation standard (ratified October 2009) to improve network throughput over the previous standards with a significant increase in the maximum raw data rate from 54 Mbit/s to 600 Mbit/s with the use of four spatial streams at a channel width of 40 MHz.
When setting up a wireless network, the bandwidth capacity of the access point and the bandwidth requirements of the network devices should be considered. In general, the useful data throughput supported by a particular WLAN standard is about half the bit rate stipulated by a standard due to signaling and protocol overhead. With network cameras that support 802.11g, no more than four to five of such cameras should be connected to a wireless access point.
هنا الانواع الثلاثه بالعكس وجدت اربع انواع بس ما ادري هيا المطلوبه في الواجب ولا لا
اما بالنسبه فقره الثانيه مين افضلهم ولماذا

اما بالنسبه فقره الثانيه مين افضلهم ولماذا

from where did you find this answer? i mean which block and section

[خطوات النجاح]

تعقدت !!!!
مافهمت كيف احل
يعني الانواع الثلاث هي نختار 3 مو الاربع انواع
802.11b, 802.11g, 802.11a and 802.11n
وبعدين كل نوع نكتب له نوع من انواع الويرلس مثلا
802.11b for Bluetooth

وحل الفقرة b
فقط نختار الرسمة b واضح فيها violations عن الماسك ونكتب السبب انو noise وشوية تفاصيل
!!
